Fig. 1

Top, left to right, female cones of G. montanum, male cones of W. mirabilis and female cones of E. equisetina. Scale bars, 5 cm. Bottom, pantropical distribution of the three gnetophyte genera, compared with three conifer species that are most abundant at higher latitudes and altitudes. The range of genomes sizes (1C-values) found in the three genera comprising gnetophytes and the three conifer species are also shown (data taken from http://data.kew.org/cvalues/ and unpublished data).
